Hidden Conflicts in Finance
This lecture by Professor Raghavendra Rau (Cambridge University) inaugurates a series exploring the human side of finance. It delves into how promises—central to financial contracts—are valued, and the often-hidden conflicts embedded in financial systems, especially those arising from principal-agent dynamics, intermediaries, and the emergence of private money like stablecoins.
🎯 Conclusion
Finance, at its core, revolves around valuing promises—whether from companies, governments, or individuals—and managing the conflicts that arise from these promises. While classical finance assumes rational markets, the human side introduces behavioral and structural problems, most notably principal-agent conflicts. These conflicts arise when those entrusted to act on behalf of others (agents) may have diverging incentives from the principals they serve. Financial intermediaries, such as banks and mutual funds, play crucial roles but can also harbor hidden risks. The rise of stablecoins mirrors historical patterns in private money but raises new regulatory concerns. Ultimately, although financial systems have evolved with more formal contracts and regulations, they remain susceptible to asymmetry, behavioral biases, and complexity-driven conflicts.
🔑 Key points
📜 Finance = Promises: Financial instruments are built on promises to pay or deliver future value in exchange for money today.
⚖️ Two valuation lenses: Classical finance values using data and models; behavioral finance considers human biases and trust.
🧑💼 Principal-agent problem: When agents (executives, fund managers, etc.) act on behalf of principals (investors) but have conflicting interests.
🏦 Banks’ core roles: Banks act as matchmakers, risk managers, liquidity providers, and information processors in the economy.
📉 Bank runs: Triggered by fear, bank runs reveal vulnerabilities in the mismatch between short-term liabilities and long-term assets.
🔐 Implicit contracts: Trust-based unwritten agreements—common in long-term or high-trust relationships—can substitute for rigid contracts.
💵 Stablecoins: Cryptocurrencies pegged to fiat currencies function like banks but with looser regulation and greater run risk.
🌐 Eurodollar market: A massive, loosely regulated offshore dollar system (~$12.8 trillion) that complicates monetary control.
📊 Regulatory gaps: Financial innovations often outpace oversight, as seen with crypto and DeFi, creating new risks.
🧠 Behavioral economics: Even rational-looking systems are shaped by psychology, herd behavior, and information asymmetry.
🧠 Summary
- Finance as promises: Finance is based on exchanging money now for future commitments (stocks, bonds, insurance). Two major perspectives assess these promises: rational valuation and human behavior.
- Human side of finance: Market behavior is affected by trust, incomplete contracts, and the potential for fraud, complicating valuation and decision-making.
- Role of financial intermediaries: Banks and funds reduce transaction costs, offer liquidity, transform maturity, and assess risk on behalf of individuals and businesses.
- Principal-agent problem: Occurs when those making decisions (agents) have incentives that diverge from those providing the capital (principals), evident across finance, real estate, and politics.
- Mechanisms to control agents: Contracts, legal regulations, and reputational dynamics are used to align interests, though none are foolproof.
- Value of implicit contracts: In trust-based or flexible settings, unwritten rules (e.g., job security or customer loyalty) can be more effective than formal agreements.
- Bank functions and profits: Banks profit from interest spreads, maturity transformation, and payment facilitation. Their lending increases money supply.
- Preventing bank runs: Tools include deposit insurance, capital and liquidity requirements, and central bank backstops. Yet digital finance introduces new risks.
- Rise of stablecoins: Digital fiat-pegged currencies like USDC and USDT operate like banks but lack full regulation, risking modern “crypto runs.”
- Global money creation: Commercial banks—not central banks—create most money through lending. The Eurodollar market further complicates global financial control.
*********
What is the principal-agent problem in finance?
The principal-agent problem arises when one party (the principal) hires another (the agent) to act on their behalf, but the agent’s interests may not align with the principal’s. For example, shareholders expect CEOs to maximize shareholder value, but CEOs might prioritize personal benefits instead.
How do financial intermediaries like banks add value to the economy?
Banks match savers with borrowers, transform short-term deposits into long-term loans, manage and spread risk, produce financial information, and provide liquidity. These functions enable efficient capital allocation and smoother economic activity.
What mechanisms exist to control agents in financial relationships?
Controls include explicit contracts (e.g., performance-linked pay), legal regulations (e.g., fiduciary duties, financial disclosure laws), and implicit contracts based on reputation and repeated interactions. A mix of these methods is often used.
Why are implicit contracts important in finance?
Implicit contracts are unwritten understandings based on trust, commonly found in long-term business relationships, mentorships, or professional services. They offer flexibility where formal contracts are too rigid or costly to enforce.
What causes bank runs, and how can they be prevented?
Bank runs occur when depositors withdraw funds en masse, fearing bank insolvency. Preventive measures include deposit insurance, capital and liquidity requirements, and central banks acting as lenders of last resort.
How do banks make money?
Banks earn through the interest rate spread—paying lower interest on deposits than they charge on loans. They also profit from fees, investment returns, and money creation via lending (the money multiplier effect).
What are stablecoins, and why are they significant?
Stablecoins are cryptocurrencies pegged to traditional currencies (like the US dollar) to maintain price stability. They facilitate fast digital transactions but carry risks due to lack of regulation and reserve transparency.
How does the Eurodollar market affect global finance?
The Eurodollar market involves U.S. dollars held in foreign banks, creating a parallel financial system. With an estimated size of $12.8 trillion, it influences global interest rates and undermines centralized monetary control.
Do central banks control the money supply?
Not entirely. Most money is created by commercial banks through lending. Central banks influence money supply indirectly through interest rates and reserve requirements but don’t directly control all money creation.
How has finance changed in the modern era?
Finance has shifted from trust-based local systems to global, regulated, and digitized networks. Despite formalization, new conflicts and asymmetries have emerged due to complexity, technology, and information gaps.
🎯 Key Takeaways (a.k.a. things you should know but probably won’t remember):
1.
Finance = Promises. Promises = Risk.
From stocks to insurance, everything is built on promises for future payouts. The real game is figuring out if the people making those promises are lying, stupid, or both.
2.
Classical vs. Human Finance:
- Classical finance is the MBA fan fiction version: efficient markets, DCF models, and spreadsheet-induced confidence.
- Human finance is actual reality: deception, incomplete contracts, asymmetric information, and the persistent hope that your fund manager isn’t just chasing his quarterly bonus.
3.
Principal-Agent Problem:
This is the academic way of saying: “People paid to act on your behalf often do what’s best for them instead.”
- CEOs redecorate their egos with shareholder money.
- Fund managers swing for the fences to earn bonuses.
- Politicians forget your name right after elections.
It’s like hiring a dog to guard your sandwich.
4.
Financial Intermediaries Are Supposed to Help…
…but they also create massive conflict potential. They:
- Match savers and borrowers (useful).
- Transform short-term deposits into long-term loans (risky).
- Manage risk via pooling (debatable).
- Pretend to be experts with your money (sometimes true).
- Add liquidity… until they don’t.
5.
Banks Are Giant Risk Factories:
They create money by lending more than they have. They profit from the interest rate spread, and when things go bad, they get government bailouts because… well, capitalism but make it inconsistent.
6.
Bank Runs: Still a Thing!
Northern Rock, Silicon Valley Bank, etc.—they prove we haven’t learned anything. Deposit insurance exists to calm the peasants, but moral hazard lives rent-free in boardrooms.
7.
Stablecoins: Crypto’s Weird Banking Cosplay
- Pretend money backed by maybe-money.
- Still prone to runs (TerraUSD says hi).
- Poorly regulated but highly influential.
- If they collapse, we all get to pretend we didn’t see it coming.
8.
The Money Supply Isn’t Really Controlled by the Central Bank:
Shocking, I know. Most money is created by commercial banks via lending. The Fed adjusts interest rates, but the Eurodollar market operates like a drunk cousin who can’t be grounded because he lives abroad.
🧠 Financial Advisor Commentary:
This lecture is an important reminder for investors, analysts, and regulation fetishists alike: finance is fundamentally human, and therefore fundamentally flawed.
The more layers you build to protect against risk—legal contracts, regulation, performance metrics—the more creative people get at exploiting loopholes. Even well-meaning systems eventually become bureaucratic mazes or tools of manipulation.
As a senior financial advisor, I’d say this lecture is a must-read for anyone who thinks compliance and modeling are enough. It reminds you to look behind the curtain, question the incentives, and not assume your fiduciary actually remembers what that word means.
🔚 Bottom Line:
You want safety? Buy Treasury bonds. You want real financial insight? Understand human behavior, not just spreadsheets. And maybe don’t trust a stablecoin named after a Roman god if you’re storing your retirement in it.
